I appreciate all your support. It has given me a lot to think about. I do have several amps. It will probably be a while before I actually build a system. I have the 2216s but still need the horns and adapters. My main goal right now is to get the parts before they are no longer available.
Right now I'm building a test stand for my 2441s and 2311 horns to see if it's worth while to integrate them in the 4344s. The shorter horns will better line up the 2235 and 2122 magnets and help remove the delay of using 2307 horn. It will be interesting to hear the difference.
Another project that is in the works is a DD55000 clone. I have pair of NOS E145s, 077s, and 2425hs but only have one 4660 horn. Not sure when and if I will find another one.
